摘　　要：[目的]掌握内蒙古某大型牲畜交易市场绵羊肠道蠕虫的感染情况。[方法]2020年7月—2021年6月逐月收集该市场绵羊粪便样本12次,共1082份,采用饱和蔗糖溶液漂浮法进行虫卵检查,对绵羊感染的肠道蠕虫卵进行形态学鉴定。采用统计学方法比较不同月份、年龄、性别绵羊肠道蠕虫感染率差异。[结果]282份粪便样本呈蠕虫卵阳性,感染率为26.1%(282/1082)。鉴定出6种蠕虫,以圆线虫为主要感染虫种,感染率为16.5%(179/1082);鞭虫、莫尼茨绦虫、细颈线虫、蛲虫和钩虫的感染率分别为7.8%(84/1082)、3.2%(35/1082)、1.9%(21/1082)、0.6%(7/1082)和0.1%(1/1082)。10月和11月绵羊的肠道蠕虫感染率较高,分别为47.4%(45/95)和43.7%(38/87);1月和2月绵羊的肠道蠕虫感染率较低,分别为13.0%(12/92)和12.2%(11/90);不同采样月绵羊肠道蠕虫感染率统计学差异极显著(χ^(2)=63.957,df=11,P<0.01)。≤6月龄、7~12月龄和>1岁的绵羊肠道蠕虫感染率分别为14.5%(56/385)、31.1%(161/517)和36.1%(65/180),不同年龄段绵羊肠道蠕虫的感染率统计学差异极显著(χ^(2)=42.853,df=2,P<0.01)。公羊和母羊的肠道蠕虫感染率分别为24.3%(102/420)和27.2%(180/662),无统计学差异(P>0.05)。[结论]该牲畜交易市场绵羊肠道蠕虫感染与季节、年龄有关,应针对性确定防治方案。[Objective]This study aimed to understand the status of intestinal helminth infections in sheep in a large livestock trading market in Inner Mongolia,China.[Method]From July 2020 to June 2021,a total of 1082 fecal samples of sheep in the livestock trading market were collected 12 times month by month.The eggs were examined by saturated sucrose solution floating method,and morphological identification of the helminth eggs found in sheep was subsequently carried out.The infection rates of intestinal helminth in sheep of different ages and genders among varied sampling months were statistically compared.[Result]There were 282 fecal samples were positive for helminth eggs,with an overall infection rate of 26.1%(282/1082).Six species of helminths were identified,of which Strongylodes was the dominant species,with an infection rate of 16.5%(179/1082).The infection rates of whipworm,Moniezia,Nematodirus,pinworm and hookworm were 7.8%(84/1082),3.2%(35/1082),1.9%(21/1082),0.6%(7/1082)and 0.1%(1/1082),respectively.The intestinal helminth infection rates of sheep were higher in October and November,at 47.4%(45/95)and 43.7%(38/87),respectively,and lower in January and February,at 13.0%(12/92)and 12.2%(11/90),respectively.The differences in intestinal helminth infection rates between different sampling months were statistically significant(χ^(2)=63.957,df=11,P<0.01).There were statistically significant differences(χ^(2)=42.853,df=2,P<0.01)in intestinal helminth infection rates among the sheep aged 6 months or less,7 to 12 months,and beyond 1 year,which were 14.5%(56/385),31.1%(161/517),and 36.1%(65/180),respectively.There was no statistically significant difference in intestinal helminth infection rates between ram and ewe(P>0.05),which were 24.3%(102/420)and 27.2%(180/662),respectively.[Conclusion]The intestinal helminth infection in sheep in the livestock trading market was related to season and age.The targeted preventative and control strategy should be taken.
